プロピレン/エチレン・ランダム共重合体、成形材料および成形品

Japanese Patent JP3791334

B2

The present invention provides propylene/ethylene random copolymers characterized in that: an ethylene content (Ew) is 0.1-10 wt%, a relationship between an isolated ethylene content (E1) and the ethylene content (Ew) is represented by the following equation $2,1-\; and\; 1,3-propylene\; units\; present\; in\; a\; polymer\; chain\; are\; 0-1\; mol\%,\; a\; weight\; average\; molecular\; weight\; (Mw)\; is\; in\; the\; range\; of\; 40,000-1,000,000,\; and\; a\; ratio\; (Mw/Mn)\; of\; the\; weight\; average\; molecular\; weight\; (Mw)\; to\; a\; number\; average\; molecular\; weight(Mn)\; is\; in\; the\; range\; of\; 1.5-3.8.\; The\; copolymers\; are\; suitable\; for\; a\; base\; resin\; for\; a\; molding\; material\; for\; the\; production\; of\; a\; wide\; variety\; of\; molded\; articles\; which\; are\; high\; in\; randomness\; and\; excellent\; in\; stiffness,\; heat\; resistance\; and\; transparency.\mathop{\mathrm{image}}$
